Application filed October 3, 1898; Serial lilo 692,569. iNo model.) I 7To all whom it may concern: I Be it known that 1, Lucas EDEL, of thecity of St. Louis, State'of Missouri, have invented certain new anduseful Improvements in Ranges, of which the following is a full, clear,and exact description, reference being had to the accompanying drawings,forming a part thereof.

Myinvention relates to ranges; and it (3011f.

sectional view taken approximately on the line 4 4 of Fig. 1.. Fig. 5 isa vertical sectional View taken approximately on the line 5 5 of Fig. 2.the upper corner of the stove, said view being taken in the directionindicated by the arrow 6, Fig.2.

In the construction of my improved range I employ a rectangular body 1,which is formed of suitable sheet metal, which body is closed at thelower end by the plate 2 andat'its upper end by a cast top 3, in whichtop are formed the usual stove-openings 4. Located within the body 1 isa seco'ndrectangular sheet-metal body 5, the same being somewhat jsmaller than is the sheet-metal bodyl, and the front and rear edges ofthis second body 5 are flanged and secured to the front and rear wallsof the body 1. Thus a space or fine 6 is formed between the bodies 1 and,5. Located in the upper right-hand corner of this second sheet -met-albody 5 and extending from the front wall of the body 1 to the rear wallthereof is an L-shaped sheet-metal plate 7, which, combined with aportion of the top and side wall of the sheet-metal body 5, forms arectangularspace, in the top of which are located the plates 8, formingthe fire-box of my improved range, sThe side plates of the firebox aresome distance away-from the upper end of the side wall of the body 5 andthe upper-end of the vertical portion of the L-' shaped plate 7 in orderto form the chambers 9. l-Iorizontallyarranged perforated plates 10 arearranged immediately beneath Fig. 2 is a top- Fig. 6 is a rear elevationof the lower ends of each of the side plates 8 of the fire-box, saidperforated plates 10 extending'from said plates 8 to the side wall ofthebody5 and to the vertical portion of the plate 7. Grate-bars 11 arerotatably arranged immediately beneath the fire-box, and located in thespace immediately beneath the plates 10 and the grate-bars is'theash-pan 12. Ar-

ranged between the upper end of the righthand one of the side plates 8of the fire-box and the top plate 3 of the range is a partition '13, inwhich is formed, an opening le, the same being normally closed by adamper 15. The shaft 16,.upon which this damper hinges, extendsoutwardly through the front wall'of the range and is there provided with:an operating-handle 17. Y An angular casing 18 is formed on or fixed tothe upper rear corner of the hodyl'immediately behind the fire-box, andsaid cas-v ing forms a chamber or passage 19, that leads from the upperright-handcorner of the passage orflue 6 to the, pipe 20, that leadsfrom the range to the chimney. 1

21 indicates a horizontally-arranged partition that is located betweenthe right-hand side walls of the bodies 1 and 5 at a point on a linewith thecenter of the fire-box, said partition extending from the lowerend of the angular casing 18 toward the front of the stove andterminating a short distance from the front wall thereof.

Formed in the front wall of the body 1, immediately in front of thefire-box, is an opening 22, and formed in the front and rear walls ofsaid body 1 at the ends of the chambers 9 are therectangular openings23.

A rectangular plate 24 is located upon the 'front of thebody 1immediately in front of last-mentioned openings 27 bei'ng normallyclosed by slides 28. LOG%tl3B(1']J pOD the rear wall of the body 1 andimmediately behind the firebox is a plate 29, in which are formedopenings 30, that communicate with the openings 23, formed in the rearwall of the body 1, andsaid last-mentioned openings 30 are normallyclosed by slides 31. A hinged door 32 is arranged upon the lower portionof the plate 24, which door closes an opening formed in the front of thebody 1 immediately beneath the fire-box, through which opening is passedthe ash-pan 12. The en-' tire space in the lower portion of the body 5is intended to be used as an oven, the door 32 for said oven beinghinged to the front wall of the body 1.

The operation and use of my improved range are as follows: When the fireis first started in the fire-box of said range, the damper 15 is turneddown, as indicated by dotted lines in Fig. 3, and the slides 28 and 31are partially withdrawn. The draft to the fire within the fire-box willenter through the openings 23, pass through the chambers 9, downwardlythrough the perforations in the plates 10, and from thence upwardlythrough the grate-bars 11, through the fire within the fire-box, andfrom thence out through the opening 14: into the passage or flue 19, andfrom thence to the pipe that leads to the chimney. This may be termedthe direct draft of the range. After the fire has become well startedand it is desired to heat the oven of the range or to heat vesselslocated in the stove-holes in the range-top the damper 15 is swungupwardly, so as to close the opening 14, and the draft from the fire-boxwill pass along the under side of the rangetop downwardly between theleft-hand walls of the bodies 1 and 5, beneath the under side of thebody 5, then upwardly between the right-hand walls of the bodies 1 and5, through the opening in front of the horizontal partition 21, and fromthence rearwardly through the chamber or passage 19 to the pipe thatleads to the chimney. Thus all of the smoke and other products ofcombustion from the fire, together with most of the heat therefrom, willpass entirely around the oven, and said oven will thereby becomeVeryquickly heated. The cold air after entering the draft-openings 23strikes against the side walls 8 of the fire-box, and thereby becomesthoroughly heated before passing downwardly through the perforatedplates 10 and into the fire.

This is an important feature, inasmuch as there is a great advantagegained by delivering a hot draft to the fire instead of a cold draft. Byproviding draft-openings in both the front and rear walls of therange-body the draft to the fire can be very accurately regulated.

A range of my improved construction is economical in the consumption offuel, provides a uniform heat to all parts of the oven, and said rangepossesses superior advantages in point of simplicity, durability, andgeneral efficiency.

Owing to the fact that the draft of cold air strikesdirectly against theside walls of the fire-box said side walls will not burn out quickly orbecome warped from great heat, owing to the fact that their exterior orouter surfaces are constantly subjected to a draft of cold air.

I claim A range, constructed with a rectangular sheet-metal body, asecond rectangular sheetmetal body arranged within the first-men tionedbody in such a manner as to form a continuous passage between saidbodies, an L-shaped plate arranged in the upper righthand corner of thesecond-mentioned sheet metal body, a fire-box located in the upperportion of the space formed by the location of the L-shaped plate, avertically-arranged partition located between the upper end of theright-hand side of the fire-box and the range-top, in which partition isformed an opening, a damper normally closing said opening there beingdraft-openings formed in the front and rear wall of the range-body ateach side of the fire-box, and sliding plates normally closingsaiddraft-openings, substantially as specified.

In testimony whereof I aflix my signature in presence of two witnesses.

LUCAS EDEL.
